I always keep an extra coat and a blanket in the car. In my truck it's a whole different story- there's a tool box full of crap in the truck. I figure the car has Onstar- might as well use it if something goes south!

I keep a tire iron in the back seat for defense. It's color-coordinated black to match the interior (just by happy coincidence.)

Unless there's been a way around it posted, there's no way to have a spare tire in the SS because the 20" tire won't fit in the trunk and a donut won't fit over the Brembo brake system. So nothing in the trunk.

Besides the factory air compressor and fix a flat in the trunk, I have a Gorilla extendable lug wrench, a emergency kit (with a flash light, rain poncho, jumper cables, triangles, and glow in the dark sticks), a tool set (with various wrenches, sockets, ratchets, and screwdrivers), and an ice scraper. Up front I have a Springfield XD 9mm subcompact.

microfiber towels, water.. That's about all for now. When it gets colder I'll have boots and a snowsuit along with a shovel in case I run off the road or somebody else needs help digging themselves out. and I have a flashlight in the glove box in case I get a flat at night.
